Quarter-Turn to Trek Blendr Light Mount - Saddle Bag Adapter
Allows you mount any quarter-turn bike accessory to a Trek Blendr light mount. I'm using it to mount a rear tail light to my Trek Blendr saddle bag.
There's two models. The 1st works great, but try the 2nd "tight clearance" model if you need a tighter fit for the quarter-turn mount. Prepare to spend some time removing support material after printing. It's a touggh shape to print.
